CAR-DOOR LOCK.

Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed September 19, 1911. Serial No. 650,287.

To all whom it may concern:

Be it known that I, CHARLES L. ALDEN, a citizen of the United States,residing at Albany, in the county of Albany and State of New York, haveinvented new and useful Improvements in Car-Door Locks, of which thefollowing is a specification.

The general object of the invention is to interlock a car door latchwitha keeper and lock the latch against movement, and lock the means forlocking the latch with the ordinary sealing device.

Other objects will appear and be better understood from the followingdescription taken in connection with the accompanying drawings, inwhich,

Figure 1 is a front elevation of a portion of the side of a carincluding the door showing my device in operative position. Fig. 2isadetail vertical section of the engaging end of the latch and keepershowing the parts in locked position. Fig. 3 is a similar view of thestaple. Fig. 4: is a similar view of the latch. Fig. 5 is an enlargeddetail perspective of the means for locking the door. Fig. 6 is asectional plan on the line 77 of Fig. 1.

Referring to the drawings, A indicates a door frame having the door 8slidable therein, said door frame having connected thereto the latch 11,said latch being pivotally supported at one end by the limb 12 of astaple 13. The staple 18 is connected to the plate 15 which is securedin any preferred manner such as by a bolt 18 to the door frame.

The tie strap 19 is suitably secured to the door such as by pins orbolts 20, and serves as an auxiliary tie for the various door par-.titions 21 to which it is secured. The keeper 22 is adapted toreceivethe nose 23 of the latch 11 and carries a locking pin, which hasa side portion 24 rotatable in the keeper 22. The said side portion 24has a segmental recess 25 the floor of which alines with one side of thehole in the keeper for the nose 28 of the latch when the pin is turnedinto one position, whereby, to permit the nose 23 to enter the keeper.The nose 23 has a recess 26 which alines with the recess 25 when thesaid nose first enters the keeper 22. When the portion 24 is turned soas to move its recess 25 away from the recess 26 of the nose 23, theportion of the side 24- opposite to the recess 25 will move into therecess 26 of the nose, whereby, the latter will be locked againstoutward movement from the keeper. The other side portion 27 of thelocking pin depends substantially vertically downward when the latch isengaged by the portion 24' as previously described. When so positionedthe side portion 27 is between the keeper and a lug 28 carried by thetie strap 19, the lug serving as an abutment to prevent longitudinalmovement of the pin when the latch is disengaged from the keeper and hasits side portion 27 extending downwardly. The lug 28 has a slot (notshown) which alines with a slot 30 in the side portion 27 and theseslots receiving the wire 31 of a seal 32. The lug 28 also has a recessabove the slot 29 which forms a passage through which the pin isintroduced into the keeper. 29 indicates a bolt or abutment extendingthrough the car door and screwed into a nut 28 which prevents removal ofthe pin. 32 indicates an overhang portion on the keeper which limits theturning movement of the side 27 of the pin.

From the foregoing it will be evident that when the several parts of thedevice are ar ranged as shown in Fig. 6 the latch will be held fromflying upwardly and outwardly and exerting any strain on the sealingdevice. From these positions, the parts, after removing the seal, may beunlocked by turning the locking pin in the proper direction when thecars bump together. It will be further observed that the parts are interchangeable, that is to say, the parts shown in Fig. 1 as applied to adoor, which closes by a sliding movement toward the left in Fig. 1, maybe also applied to a door sliding in the opposite direction to closedposition.

Although I have shown and described one embodiment of my invention it isto be understood that I am not to be limited to the specific structureherein shown nor to the particular arrangement of the parts, since itwill be seen that various changes may be made, within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

What I claim as new is:

1. In a car door lock, in combination with a door and door frame, of arecessed seal holder carried by the door, a keeper arranged adjacent tothe seal holder, a latch pivoted to the door frame and adapted tointerlock with the keeper, means associated with the keeper'for lockingthe latch therein, and having a recess to aline with the re oess of theseal holder. o

2. In a car door look, a pivoted latch having a nose, a keeper forreceiving the nose, a rotary bolt carried by the keeper, and meanscarried by the nose and the bolt adapted to interlock when the nose isin the keeper and the bolt turned in one direction.

3. In a car door look, a latch, a keeper for receiving the latch, arotary bolt for locking the latch in the keeper, a seal holderpositioned at one endof the bolt and forming a stop for the bolt whenthe same is turned into one position and moved longitudinally and havinga recess to admit of the passage of the bolt t-herethrough when the sameis turned into another position and moved longitudinally.

,admit 4. In a car door look, a latch, a keeper for receiving the latch,a rotary bolt for locking the latch in the keeper, a seal holderpositioned at one end of the bolt and forming a stop for the bolt whenthe same is turned into one position and moved longitudinally and havinga recess to of the passage of the bolt therethrough when the same isturned into another position and moved longitudinally, and an abutmentlocated in the recess and removably secured to the seal holder for thepurpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
